281-05964

The Siemens 281-05964 is a 2-way normally-open control valve assembly that incorporates an efficient pneumatic actuator. Weighing 211 lbs, the valve is robustly built to handle various applications. This assembly is characterized by its significant flow coefficient rating of 400 Cv, which allows for optimized flow control in diverse settings.

Designed with a 6-inch diameter valve size, it enables significant media passage while its actuator type, a diaphragm of 12 inches, ensures dependable operation. The diaphragm supports a maximum pressure of 35 psi and operates with a fixed spring range of 5 psi, providing stability in performance. The media temperature that this valve can accommodate ranges from -4 to 186°C, leveraging its high-temperature version for demanding scenarios.

The actuator features a stroke length of 40 mm (1-1/2 inches), facilitating precise adjustments in flow. An air connection of 1/4 inches NPT provides straightforward integration into existing systems. Additionally, the valve operates with a flow characteristic defined as equal percentage, ensuring effective modulation across its range. The trim material made of stainless steel promotes durability and corrosion resistance, making the Siemens 281-05964 suitable for various industrial applications.
